JOSEPH LEAOH, OFYINDIANAPOLIS, ASSIGNOR OF ONE-HALF TO CALVIN G.

UDELL, OF NORTH INDIANAPOLIS, INDIANA.

HOOP FOR COOPERS WARE.

SPECIPICATION forming part of Letters Patent No. 376,530i dated January 1'7, 1888. Application filed September 172, 1887. Serial No. 149,412. (No model.)

To all whom it may concern:

Be it known that I, J osEPH LEAoH, of Indianapolis, county of Marion, and State of Indiana, have invented certain nev7 and useful Improvements in Hoops for Coopers Ware; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, in which like letters refer to like parts.

My invention relates to the construction of metal hoops for coopers Ware, and will be understood from the following description.

In the drawings, Figure 1 represents a sectional view of'a tub upon which my hoops are placed. Fig. 2 is an edge view of the hoop itself. Fig. 3 is a section on the line y y, Fig. 2.

In detail, t is the tub, made in the usual manner. h is the hoop, which may be made of either one or two pieces of metal, and is provided with one or more spurs, s, on the i`nside, having knifeedges, as shown in Fig. 2. One of these spurs may be conveniently made by upsetting the end of the hoop beyond the rivet, while the other, if the hoop is made of one piece, may be fastened on by an eXtra rivet, as shown in Fig. 2. The hoop is preferably made of ordinary iron, and if used upon a daring vessel will flare correspondingly.

The' object of this improvement is to prevent the hoop from falling off the vessel when the latter shrinks, which is the invariable result when the ordinary hoop is used.

I form the hoop with the spurs, as before described, these spurs being bent at right an gles to vthe inner face of the hoop, and they can be driven into a stavey and will hold the hoop upon the vessel. rlwo of these spurs are sufficient, 'and in some cases one is enough; but two are generally preferable. When the hoop is formed ready to put on, it is placed in position for driving it on the vessel, letting it go asnear to where it will bind all of the staves as the spurs will allow. Then 'with any sharp instrument an opening is made in the stave where the spur comes in contact with it, so

` that the edge of the spur will enter the opening thus made Without driving, and the hoop can be driven to Where it must remain by an ordinary instrument. The spurswill cut their own grooves up the wood as the hoop is dri-ven to its proper place, and the Wood will close up behind the spur without showing any indentation or marks, as the spurs are made with a knife-edge. i

I am aware that hoops provided with angular spurs or points struck out of the kbody of the hoop have been heretofore made, and that auxiliary devices for spurs, one part encom-l passing the hoop, have been also used, and do not claim the same as my invention.

What I claim as my invention. and desire to secure by Letters Patent, is the following:

1. A met al hoop for barrels or casks, formed of asingle piece of metal, the end of the inner lap upset to form a spur for engaging with the sides of the tub and preventing the hoop from fallingoff, substantially as described.

2. TheA hoop h, formed of a single piece of metal, the end of the inner lap upset to form a spur, s, and an additional spur bolted tothe inside ofthe hoop at a point opposite such lapped end, substantially as shown and described.

In Witness whereof I have hereunto set myv hand thisjth day of September, 1887.
